Via David Codrea, this decision.
The Supreme Court has been careful to note that “longstanding prohibitions” like “laws forbidding the carrying of firearms in sensitive places such as schools and government buildings” remain “presumptively lawful.” Heller I, 554 U.S. at 626, 627 n.26…. [T]he same security interests which permit regulation of firearms “in” government buildings permit regulation of firearms on the property surrounding those buildings as well…
Second, the lot is close to the Capitol and legislative office buildings. Class possessed a firearm less than 1,000 feet away from the entrance to the Capitol, and a block away from the Rayburn House Office Building. Although there is surely some outer bound on the distance Congress could extend the area of protection around the Capitol without raising Second Amendment concerns, Congress has not exceeded it here.
Finally, as the owner of the Maryland Avenue lot, the government—like private property owners—has the power to regulate conduct on its property. See [Adderley] v. Florida, 385 U.S. 39, 47 (1966) (observing in the free-speech context that the government, “no less than a private owner of property, has power to preserve the property under its control for the use to which it is lawfully dedicated”); cf. Bonidy v. U.S. Postal Serv., 790 F.3d 1121, 1126 (10th Cir. 2015) (observing that when the U.S. Postal Service acts “as a proprietor rather than as a sovereign, [it] has broad discretion to govern its business operations according to the rules it deems appropriate”).
There are no interests in the regulation of firearms in government buildings or “sensitive” places. That’s a figment of the imagination. Criminals don’t obey the law, so a regulation won’t be enough to stop someone bent on evil. Anyone intent on violating the prohibition on murder will gladly violate a prohibition on firearms possession.
So the first two paragraphs are pure mythology. As for the third paragraph, I find myself in agreement. Property rights supersede the RKBA on private property unless the government forces our presence on that private property. For patrons of that parking deck, they should find another place to park.
EDIT: I see that by posting late and mis-reading the text I feel into their trap. I still support property rights above everything, but in fact the FedGov does not have property rights. They shouldn’t even own property. My initial reading of the text indicated to me that a private corporation owned the parking deck. That isn’t the case.
